22/30 = 11/15
7/9 = 14/18
18/54 = 1/3
10/17 = 20/34
A proportion can be set up by using the general formula:
a/b = c/d
ad = bc
Evaluate all the absolute value first.
|-7|=7
|4|=4
Rewrite and solve using the order of operations

Final answer: 19
Given :
Amount of cereal in smaller box , 6 + 7.1 .
Amount of cereal in big box , 12 + 6.9n ( here , n is number of small boxes ).
To Find :
The amount of cereal that the new larger boxes contains how many smaller boxes equal the same amount of cereal in the larger box.
Solution :
Let, number of boxes required to satisfy given condition is x.
So,
Therefore, two small boxes are required.
Hence, this is the required solution.
3(2x+5)=3
3 • 2x] + [3 • 5] = 3
6x + 15 = 3
6x = –12
x = –2
2x – 2(3x – 2) = 2(x –2) + 20
2x – 2(3x – 2) = 2(x –2) + 20
2x – 6x + 4 = 2x – 4 + 20
– 4x + 4 = 2x + 16
–4x + 4 – 4 –2x = 2x + 16 – 4 -2x
–6x = 12
x = –2
